Annihilators of Bounded Indecomposable Modules of Vec(R)

Description: The Lie algebra Vec(ℝ) of polynomial vector fields on the line acts naturally on ℂ[]. This action has a one-parameter family of deformations called the tensor density modules F_λ. The bounded indecomposable modules of Vec(ℝ) of length 2 composed of tensor density modules have been classified by Feigin and Fuchs. We present progress towards describing the annihilators of the unique indecomposable extension of F_λ by F_(λ+2) in the non-resonant case λ ≠ -½. We give the intersection of the annihil… more

Antigravity

Description: This dissertation contains two parts: Part I, which discusses the elegy of possessive intent, a subgenre of the contemporary American elegy; and Part II, Antigravity, a collection of poems. English elegies have been closely rooted to a specific grief, making the poems closer to occasional poems. The poet—or at least the poet’s speaker—seeks some kind of public consolation for (often) a private loss. The Americanized form does stray from the traditional elegy yet retains some of its charact… more

Antonín Dvořák’s Piano Concerto in G Minor, Opus 33: A Discussion of Musical Intent and Pianistic Effectiveness in Vilém Kurz's Version of the Solo Piano Part

Description: Since its premiere in 1878, Antonín Dvořák’s Piano Concerto in G Minor has been underrated and held in low regard by musicologists, critics, performers and audiences alike. Vilém Kurz (1872-1945), a Czech pianist and pedagogue, revised and reworked the piano solo part to incorporate what he considered to be added brilliance and pianistic effectiveness. However, the revised version has not increased the popularity of the work. In recent decades, this concerto has begun to appear more often in th… more
